4 x 11 W single-ended car radio power amplifier

FEATURES
Requires very few external components Flexibility in use Quad single-ended or stereo BTL High output power Low offset voltage at output (important for BTL) Fixed gain Good ripple rejection Mute/stand-by switch Load dump protection AC and DC short-circuit-safe to ground and VP Thermally protected Reverse polarity safe Capability to handle high energy on outputs (VP = 0) Protected against electrostatic discharge No switch-on/switch-off plop Flexible leads Low thermal resistance Identical inputs (inverting and non-inverting).
